Leitoscoloplos cf. abranchiatus (Hartman, 1967a) Fig. 18B

Diagnosis.

All specimens incomplete posteriorly. Longest fragment ~ 15 mm long, 1.3 mm wide, consisting of 41 chaetigerous segments. Thorax slightly flattened, abdomen cylindrical. Prostomium conical; one peristomial ring. Eleven thoracic chaetigers. Abdominal parapodia lateral in anterior abdomen, shifted dorsally on posteriorward segments. Branchiae from chaetiger 24, first short triangle, then becoming longer, strap-like. Thoracic postchaetal lobes conical in both rami; short in anterior thorax, becoming longer in middle and posterior parts; notopodial lobes longer. No subpodial or stomach papillae. Abdominal notopodia digitiform, same length as branchiae or shorter; abdominal neuropodia weakly bilobed, with short round lobes, inner slightly larger. Subpodial flange not developed, no flange papillae. All chaetae crenulated capillaries; forked chaetae not observed, probably broken. Colour in ethanol whitish-brown, with pigment spots on prostomium and in intersegmental furrows, or completely white.

Remarks.

Leitoscoloplos abranchiatus was described as entirely lacking branchiae, but all specimens studied were posteriorly incomplete (Hartman 1967a; Mackie 1987; Blake 2017). Specimens described here resemble L. abranchiatus by the number of thoracic chaetigers, shape of thoracic postchaetal lobes, shape and more lateral than dorsal position of abdominal parapodia.
